Optimization of PID Governor Coefficient for Turbocharged Diesel Engine

The objective of this study is to find optimum governor coefficient for which fluctuation of engine speed is minimum, for given value of engine, turbo-charger, inlet and exhaust manifold characteristics. Current study uses the Wishnegradski Stability Diagram as suggested by V. I. Krutov [1], which graphically represents the dynamic response of governor based on the engine differential equation which is of the third order. For the load type of L = B cos (wt): The objective function is designed to minimize the integral squared error over a time period T, which is taken as 5seconds. The constraints are formed using Wishnegradski Stability Curves which are mathematically represented as x > 0 and xy – 1 > 0 y > 0, where x, y are non-dimensional parameters depending on engine characteristics and Ne is the error function. From the experimental data obtained by test on a marine turbo-charged, 6 cylinder engine model KTA-1150C-600 of the Kirloskar make, the optimized values of Kp, Ki and Kd were obtained as 798.94, 41.50 and 1137.4 respectively and corresponding objective function is 2.2202e-07 and amplitude of speed fluctuation is 2.6642e-04 rpm.

Performance and Emission Characteristics of Pongomia Oil using VCR Engine with Turbo Charger Setup

The diesel motors has prompted the outflow of risky gases like Sulfur oxides, nitrogen oxides and carbon monoxide, which can additionally prompted issues like acid rain, These discharges can likewise influence human well being and increment a dangerous atmospheric devation which has prompted the requirement for interchange energizes. Biodiesel is one of the choices which are by and large broadly considered and its generation from oil seeds is constrained by yield land dislodging, The impact of variable pressure proportion at various burdens with turbocharger is utilized to break down the presentation and to improve the exhibition of an I.C motor and to expand the effectiveness of the single chamber four stroke diesel motors. The turbocharger is utilizations to the vitality of fumes gas to drive more air-fuel blend into chamber to expand the motor power. The properties of Pongamia pinnata oil mixes with diesel are tried in a variable pressure proportion motor (VCR motor) with turbo charger arrangement. The presentation attributes of the motor are utilized to decide the brake control, explicit fuel utilization, warm effectiveness, and so on.
